根據(jù)協(xié)議規(guī)范的要求： 1.設(shè)置觸發(fā)時(shí)間 2.設(shè)置遲滯H2a的值

When event 2a is configured in the UE within a measurement, the UE shall:
1> when the measurement is initiated or resumed:
2> store the used frequency in the variable BEST_FREQUENCY_2A_EVENT.
1> if equation 1 below has been fulfilled for a time period indicated by "Time to trigger" for a frequency included
for that event and which is not stored in the variable BEST_FREQUENCY_2A_EVENT:
2> send a measurement report with IEs set as below:
3> set in "inter-frequency measurement event results":
4> "inter-frequency event identity" to "2a"; and
4> "Frequency info" to the frequency that triggered the event; and
4> "Non frequency related measurement event results" to the "rimary CPICH info" of the best primary
CPICH for FDD cells or "rimary CCPCH info" to the "Cells parameters ID" of the best primary
CCPCH for TDD cells on that frequency, not taking into account the cell individual offset.
3> if a non-used frequency triggered the measurement report:
4> include in IE "Inter-frequency measured results list" the measured results for the non-used frequency
that triggered the event, not taking into account the cell individual offset.
3> if the used frequency triggered the measurement report:
4> do not include the IE "Inter-frequency measured results list" in the measurement report.
3> set the IE "additional measured results" according to subclause 8.4.2, not taking into account the cell
individual offset;
2> update the variable BEST_BEST_FREQUENCY_2A_EVENT with that frequency.
Equation 1:
2 / 2a Best NotBest H Q Q + ≥
The variables in the formula are defined as followsNot Best is the quality estimate of a frequency not stored the "best frequency" in the variable
BEST_FREQUENCY_2A_EVENT.
QBest is the quality estimate of the frequency stored in "best frequency" in the variable
BEST_FREQUENCY_2A_EVENT.
H2a is the hysteresis parameter for the event 2a in that measurement.
